Cilantro stems, with their more intense flavor, should be added early in the cooking process to infuse a dish, while the delicate leaves should be added at the end to preserve their fresh, bright aroma.
Cilantro, also known as coriander leaves, is a versatile herb used in many cuisines. The stems and leaves offer distinct aromatic profiles and react differently to heat.
Cilantro Stems: Cilantro stems possess a stronger, more concentrated flavor than the leaves. They can withstand longer cooking times without losing their essence. Adding them early in the cooking process, such as when sautéing aromatics or simmering a sauce, allows their flavor to fully permeate the dish. Think of them like a subtle, herbaceous base note.
Cilantro Leaves: Cilantro leaves are more delicate and have a brighter, fresher flavor. High heat can quickly diminish their aroma and turn them bitter. Therefore, it's best to add cilantro leaves towards the end of cooking, or even as a garnish after the dish is plated. This preserves their vibrant flavor and visual appeal. They act as a bright, fresh top note.
Don't discard the cilantro stems! Finely chop them and freeze them in ice cube trays with a little water or broth for easy addition to soups, stews, and sauces. This minimizes waste and maximizes flavor.
